Notes:
1) Exceeding these ratings may damage the device
2) The maximum allowable power dissipation is a function of the
maximum junction temperature T
J
(MAX), the junction-to-
ambient thermal resistance
θ
JA
, and the ambient temperature
T
A
. The maximum allowable continuous power dissipation at
any
ambient
temperature
is
calculated
by
P
D
(MAX)=(T
J
(MAX)-T
A
)/
θ
JA
. Exceeding the maximum
allowable power dissipation will cause excessive die
temperature, and the regulator will go into thermal shutdown.
Internal thermal shutdown circuitry protects the device from
permanent damage..
3) The device is not guaranteed to function outside of its
operating conditions.
4) Measured on JESD51-7, 4-layer board.
